Today I said screw it and figured this rack wasn't worth anything to me if I couldn't turn the cylinder. I have been afraid of breaking the aluminum housing and had the rack clamped in my vise at the mounting boss. I put what I thought was a lot of torque on it with a pipe wrench but couldn't get it to turn. I decided to clamp the aluminum housing right next to the cylinder and force it until it either rotated or broke. It finally rotated with a lot of force on the pipe wrench.I almost had to get a cheater bar.
I almost decided to rotate it so the fittings faced out the BACK of the rack until I realized it wouldn't work because one fitting would hit the rack mount bracket k-member. So I rotated it forward almost 90 degrees.
Now I need to figure out the plumbing for the lines and notc.
